Discord Error 3002 appears when the app shows a red banner saying “Well, it looks like Discord is not detecting any input from your mic.” This error means Discord can see your microphone device, but it is not receiving any audio signal from it. As a result, your voice does not transmit during calls, gaming sessions, or voice channels.
Discord Error 3002 occurs when the microphone is connected but no audio input reaches Discord. This is different from cases where the mic is completely missing. Here, Discord recognizes the device but receives zero input, which triggers the error banner.
Because Discord relies on WebRTC for voice communication, any break between your microphone, operating system, and Discord’s voice service can cause Error 3002.
Quick Checks Before Advanced Fixes
Before moving to detailed troubleshooting, try these quick checks:
- Restart Discord completely
- Unplug and reconnect your headset or microphone
- Select the correct mic in Settings → Voice & Video
- Test your microphone in another app like Zoom or Voice Recorder
If the error persists, continue with the fixes below.
Fix 1: Check Microphone Permissions (Most Important)
If Discord does not have permission to access your microphone, it cannot receive any input.
On Windows 10 / 11
- Open Settings → Privacy & Security → Microphone
- Turn Microphone access ON
- Ensure Let apps access your microphone is enabled
- Scroll down and confirm Discord is allowed
- If already enabled, turn access OFF, wait a few seconds, then turn it back ON
On macOS
- Open System Settings → Privacy & Security → Microphone
- Make sure Discord is checked
- Restart Discord after making changes
Fix 2: Verify Microphone Input Device and Volume
Discord Error 3002 often occurs when the microphone input volume is set to zero, even though the device is selected correctly.
On Windows
- Go to Settings → System → Sound
- Under Input, select your active microphone
- Increase the Input Volume and make sure it is not muted
- Confirm the input level moves when you speak
On macOS
- Open System Settings → Sound → Input
- Select the correct microphone
- Increase the input level
Fix 3: Reset Discord Voice Settings
Incorrect Discord voice configurations can block microphone input.
- Open Discord → Settings → Voice & Video
- Scroll down and click Reset Voice Settings
- Reopen Discord and reselect your microphone
- Re-grant permissions if prompted
Fix 4: Disable Noise Suppression and Audio Enhancers
Discord’s noise suppression or third-party audio tools can sometimes block low-volume input.
- Go to Discord → Voice & Video
- Set Noise Suppression to None
- Disable any third-party tools like VoiceMeeter, Realtek effects, or audio mixers
- Temporarily turn off antivirus audio protection features if enabled
Fix 5: Update or Reinstall Audio Drivers
Outdated or corrupted drivers can prevent audio input from reaching Discord.
On Windows
- Press Win + X → Device Manager
- Expand Audio inputs and outputs
- Right-click your microphone → Update driver
- Restart your system
If updating does not help, download the latest driver from your PC or motherboard manufacturer’s website.
Tip: In microphone properties, disable “Allow applications to take exclusive control of this device” to prevent conflicts.
Fix 6: Run the Windows Recording Audio Troubleshooter
Windows includes a built-in tool that can automatically fix microphone issues.
- Open Settings → System → Troubleshoot → Other troubleshooters
- Find Recording Audio
- Click Run and follow the on-screen steps
Fix 7: Clear Discord Cache Files
Corrupted Discord cache files can cause Error 3002 by breaking audio detection.
- Close Discord completely
- Press Win + R, type %appdata%, and press Enter
- Delete the Discord folder
- Reopen Discord and log in again
Fix 8: Test Discord Web vs Desktop App
If the desktop app fails, try using Discord Web in Chrome or Edge.
- Visit discord.com
- Allow microphone permissions in the browser
- Select the correct mic from the address-bar device menu
If the web version works, reinstalling the desktop app may resolve the issue.
Fix 9: Check Hardware or USB Port Issues
If your microphone works on another device but not on your PC:
- Try a different USB port (rear ports are recommended for desktops)
- Avoid unpowered USB hubs
- Power-cycle external audio interfaces
- Test with a different microphone or headset
Linux Note (Optional)
On Linux systems, check PulseAudio or PipeWire settings to ensure the correct input device is selected and not muted. Restarting the audio service can also help.
When to Contact Discord Support
If Discord Error 3002 continues after all fixes:
- Confirm the mic works in other applications
- Note your OS version and microphone model
- Capture screenshots of Discord Voice settings
- Submit a request through the Discord Help Center
